Unity/VTK is only through Activiz afaik, but maybe @LucasGandel can elaborate
That’s super unfortunate. Would it be possible to develop with ActiViz on windows but then build the actual application to Mac OS or would that still cause issues with the library? What I’m thinking is that since applications like Paraview and pyVista are compatible Mac OS and I’m pretty sure they use these same libraries that would be possible.
